WebThe cells in multicellular organisms may be specialized to do different jobs and are organized into tissues, such as connective tissue, epithelial tissue, muscle, and nervous tissue. ... and these cells fuse to form a new individual with a full genetic set. This process, called fertilization, is illustrated in the image at far right. WebAll cells and tissues in the body derive from three germ layers: the ectoderm, mesoderm, and endoderm. Membranes are layers of connective and epithelial tissues that line the external environment and internal body cavities of the body. Synovial membranes are connective tissue membranes that protect and line the freely-movable joints.

WebAdult stem cells are found in a tissue or organ and can differentiate to yield the specialized cell types of that tissue or organ. Pluripotent stem cells. Early mammalian embryos at the blastocyst stage contain two types of cells – cells of the inner cell mass, and cells of the trophectoderm. The trophectodermal cells contribute to the placenta. WebBasically, a cell consists of three parts: the cell membrane, the nucleus, and between the two, the cytoplasm. The cell nucleus contains genetic material and regulates activities of the cell. It determines how the cell will function, as well as the basic structure of that cell. WebSep 8, 2024 · Cells, the smallest structural and functional unit in the human body, form tissues, which assemble into organs, which finally group into organ systems. Cells consist of two main compartments, the nucleus and the cytoplasm. All cells originate from a single cell, the zygote. chrome pdf 转 图片
